Back pressure leak detection is a method of combining filling and vacuum leak detection. In vacuum coating equipment, it is mostly used in the nondestructive leak detection technology of sealed electronic devices, semiconductor devices and other seals. The leak detection process can be divided in......

The so-called multi arc ion coating is to place the material to be plated and the substrate to be plated in the room. The multi arc ion coating of vacuum coating machine uses a certain method to heat the material to be plated, make it evaporate or sublimate, and then sputter to the surface of the......
